This O-ring is part of Sierra's Mercury Outboard O-Rings \u0026amp; Seals line and is used during gearcase service, seal replacement, and general lower unit maintenance where a reliable, leak-free seal is required. Because it is packaged in quantities of 5, it is well suited for shops or owners who want spares on hand for future service work rather than purchasing a single O-ring at a time.\u003c\/p\u003e\u003cp\u003eFitment data on file for the Sierra 18-7160-9 covers Mercury 60\/80\/90 outboard motors from 1965-1972. Always confirm the O-ring matches your gearcase application before installation, since Mercury used different sealing components across other outboard and MerCruiser sterndrive model lines.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Sierra\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 18-7160-9\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e O-Ring\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity:\u003c\/strong\u003e 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.08 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282165383\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCategory:\u003c\/strong\u003e Mercury Outboard O-Rings \u0026amp; Seals\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eMercury 60\/80\/90 outboard, 1965-1972\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat is the Sierra 18-7160-9?\u003c\/strong\u003e It is a gearcase O-ring made by Sierra, sold in a package of 5, listed under Mercury Outboard O-Rings \u0026amp; Seals.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many O-rings come in a package of 18-7160-9?\u003c\/strong\u003e Each package of the Sierra 18-7160-9 contains 5 O-rings.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat Mercury outboard models does the 18-7160-9 O-ring fit?\u003c\/strong\u003e Fitment on file for the 18-7160-9 covers Mercury 60\/80\/90 outboard motors from 1965-1972.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does a package of Sierra 18-7160-9 O-rings weigh?\u003c\/strong\u003e A package of the Sierra 18-7160-9 weighs 0.08 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-7160-9 a genuine Sierra part?\u003c\/strong\u003e Yes, 18-7160-9 is the Sierra manufacturer part number for this O-ring, sold in a pack of 5.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the UPC for the Sierra 18-7160-9 O-ring package?\u003c\/strong\u003e The UPC for the Sierra 18-7160-9 package of 5 O-rings is 808282165383.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhen would I need to replace the 18-7160-9 O-ring?\u003c\/strong\u003e This O-ring is typically replaced during gearcase service or seal replacement on applicable Mercury 60\/80\/90 outboards from 1965-1972.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy does the 18-7160-9 come in a pack of 5 instead of a single unit?\u003c\/strong\u003e Sierra packages the 18-7160-9 in quantities of 5 so owners and shops can keep spares on hand for future gearcase service.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the Sierra 18-7160-9 fit all Mercury outboards?\u003c\/strong\u003e No, fitment data on file for the 18-7160-9 is specific to Mercury 60\/80\/90 outboard motors from 1965-1972; it should not be assumed to fit other model lines.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat category does the 18-7160-9 O-ring fall under?\u003c\/strong\u003e The Sierra 18-7160-9 is categorized under Mercury Outboard O-Rings \u0026amp; Seals.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988364669147,"sku":"SIE-18-7160-9","price":12.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/18-7160-9__42561.1737847603.500.750.jpg?v=1785329173","url":"https:\/\/www.goodvibesmarina.com\/products\/mercury-outboard-fuel-pump-o-ring-replaces-oem-25-31986-sierra-18-7160-9-pack-of-5","provider":"Good Vibes Marina","version":"1.0","type":"link"}
